NAME

ypaliases − NIS aliases for sendmail

SYNOPSIS

/etc/ypaliases

AVAILABILITY

Available only on Sun 386i systems running a SunOS 4.0.x release or earlier.  Not a SunOS 4.1 release feature. 

DESCRIPTION

Create the Network Information Service (NIS) aliases map with this text file.  The /etc/ypaliases file has the same format as the /etc/aliases file described in aliases(5). 

The text file for the NIS aliases map is stored in the /etc/aliases file on the NIS master of an NIS domain.  Other systems in a domain (besides the NIS master) can also have a local /etc/aliases file.  The local file is accessed first by programs such as sendmail(8), and if it contains a line beginning with the character ‘+’, the NIS map will be accessed. 

The local /etc/aliases file can specify resources that are not available on a network-wide basis.  This implies that the NIS master cannot use the local /etc/aliases file to specify aliases that are to be known only to the local system.  Sun386i systems allow the /etc/aliases file on the NIS master to be used locally, creating the NIS aliases map with the /etc/ypaliases text file.
